SPRING-BED.

Specification 01? Letters Patent. Patented J an; 24, 1911.

Applieationflled March 3, 1910. Serial No. 547,158.

To all whom it may concern: I

Be it known that I, EDWARD Ronsnri, a

citizen of the United States,.residing at his Angeles, in the county ofLos Angeles and State of California, have invented a new and usefulSpring-Bed, of which .the following is a specification. 4

This invention relates tospring beds which are adapted to accommodatetwo persons, and the main object of the invention is tofprovide such abed with means whereby the two sides of the spring bed are renderedmoreor less independent, so that excessive weight on one side of the bedwill not materially affect the other side ofthe bed.

" Where two persons of different weights are usin a spring. bed, the bedtends tosa towart the side where the greater weight-is laced, resultingin the inconvenience of the ighter persontending to rolltoward theopposite side, and the present invention is 'dil rectedto obviate thisdefect.

Another object ofthe invention is to provide a spring bed of theabox'edcscribed character with means for substantially .cqnalizingtl'ietension orelasticity of the bed throughout its width.

Other objects of the invention will appear hereinafter.

Referring to the drawings :Figure .1 is a plan of thespring bed; withparts broken away;- Fig. 2 is a transverse section on line oa -m Fig. 1.

The bed comprises a frame having longitudinal members 1 and cross bars 2at each end thereof, and a bed spring 3 secured to and stretched between,Silld cross pieces.

Said bed. spring preferably consists of a woven wire web'orfabrichaving-its end portions gripped by suitable clamping means 4'at each endof the bed frame or otherwise secured tothe cross members 2. Said bedspring isconstructed so asto overla'p along the central portion of thebed and this is preferably effected by doubling the .woven wire back andforth on itself so as to form two oppositely extending superposed loopsor overlap portions indicated at 6, 6 in Fig. 2, said loops or overlapportions- 6 overlying the overlap portions 6'.

A reinforcing member consisting of a rope or strand Of-COllGd. wire,indicated at 7,

- extends within each of the loops 6, 6. at the "bend'thereof so thatthe bed spring 3 passes over'and around one of said ropes andthen backover and'around the other of said ropes, then forwardly below the twolayerstirst formed to the other side of the bed,

and is secured at its end by the clamping means 4 so as to efiectivelysupport the inner end of each loopand to divide the spring bed into twoportions 3', 3", the portion?! extending over one side of the bed to thebend of the loopv 6, and the portion 3 ex tending over the opposite edgeof the bed to the bend of loop'6.-

The triple thickness of web. provided at the overlaps or loops'6together with the reinforcing means 7- provides for considerably greaterstiffness at the central portion of the bed than at the side portions,and to equa,lize,'as far as necessary, the stiffness throughout thcbed,I prefer to provide ad- 5 ditional reinforcing means consisting oflongitudinal wires 8 tensioned, by coiled springs 9 secured by wires 10to the respective end members 2. The reinforcing wires 8 preferablyextend through the woven wire mesh as indicated in Fig. 2 to enable"them to more efiectively'support the bed.

A stiffening rope or reinforeim means consisting of a portion of thewidth of the spring bedrolled upon itself as shown at 10, and witha'core strand 11, is provided at each sideof the bed to stiffen the edgethereof.

' By reason of the independent support of the: two sides 3', 3 of thebed, by means of the loops 6, 6, each side of the bed may yield more orless independently of the other web is of advantage in that, in case 0saging of one side of the bed, no opening is orrned through which bedclothes or any part of the occupants person might protrude.

What I claim is: 1. A s ring bed comprisin a frame, two

"longitudinal reinforcing mem ers extending between and secured to theends of the frame near the midwidth of the bed, and a bed spring securedto and extending between the ends of the frame, said'bed spring beingbent over and around one of said reinforc-- g with the bend of each ofsaid 1oops,'and reing members, and then back over and Enforcing meansfor said elastic fabric along around the other of said reinforcing men 1each side thereof.
